Description

The present invention relates to a mattress and the like.

Conventionally, in an electric bed, back raising operation and knee raising operation are possible. However, there is a problem in that the user himself or herself may feel pain or discomfort or have an incorrect posture due to displacement or pressure generated during the back raising operation or the knee raising operation.

In order to solve these problems, various bed mechanisms and mattress structures have been invented. For example, it is possible to prevent misalignment and to easily turn over, change clothes, secure an airway during eating and drinking, awaken the body, correct the shoulder drop of a care recipient with hemiplegia, and have a high degree of freedom of tilting. An invention of a bed that allows a care receiver to maintain a comfortable posture is disclosed.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Needless to say, the contents of the present invention are not limited to the contents of the following embodiments.

[1. Functional configuration]
First, the functional configuration of the bed apparatus 1 to which the present invention is applied will be described with reference to FIG.

As shown in FIG. 1, the bed apparatus 1 includes a control unit 100, a state detection unit 110, a storage unit 120, an operation input unit 125, a back raising control unit 130, a knee raising control unit 140, and shoulder control. It is configured to have a section 150 and a fulcrum control section 160.

The control unit 100 is a functional unit for controlling the entire bed apparatus 1. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 120, and is configured by, for example, a CPU (Central Process Unit).

The state detection unit 110 is a functional unit for detecting each state of the bed apparatus 1. It is a functional unit for detecting and outputting the state of the bed apparatus 1, such as the state of the actuator and the state of the air cell. The user's condition such as the user's weight, body pressure, heart rate, etc. may be detected.

The storage unit 120 is a functional unit in which various programs necessary for the operation of the bed apparatus 1 and various data are stored. The storage unit 120 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

The operation input unit 125 is a functional unit for performing an operation input to the bed apparatus 1 so as to perform various operations. For example, it may be provided in the bed device 1 such as an operation remote controller, or may be an external device such as a linked smartphone. The means for inputting operations is not limited to hardware keys, and various means such as software keys and voice input are conceivable.

The back raising control unit 130 is a functional unit that controls the back raising motion unit 135, and the knee raising control unit 140 is a function unit that controls the knee raising motion unit 145. That is, the back-raising control unit 130 controls the back-raising operation unit 135 to perform the back-raising operation and the back-lowering operation. Similarly, the knee raising control unit 140 controls the knee raising operation unit 145 to perform the knee raising operation and the knee lowering operation.

Here, the back-raising operation and the knee-raising operation may be performed independently or may be performed in conjunction with each other. The simple back-raising operation and knee-lowering operation themselves are realized also in the conventional bed apparatus, and may be realized by any method. For example, as an example of the back-raising operation unit 135, it may be realized by moving a back bottom from a driving device such as an actuator through a link mechanism, or by tilting the bed frame, the back-raising operation is relatively performed. May be realized.

The shoulder control unit 150 is a functional unit for controlling the shoulder operation unit 155. Here, the shoulder operation unit 155 is an operation unit that is provided in the vicinity of the user's shoulder and that aims to lift the shoulder (on one side) and/or the neck. The shoulder operation unit 155 is on the left side (the user's left hand side when lying on the back) when viewed from the user, and is on the right side (the user right hand side when the user is on the back) viewed from the opposite user. It has an R shoulder operating portion 155R.

The fulcrum control unit 160 is a functional unit for controlling the fulcrum operation unit 165. Here, the fulcrum control unit creates a portion that comes into contact with the user so that the fulcrum of the motion of the user's body is made in a part of the lower leg when the upper body is rotated. It is provided in. That is, the fulcrum operation unit 165 lifts the patient's thigh or buttocks.

The fulcrum operation unit 165 is on the left side (the user's left hand side when lying on the back) when viewed from the user, and the L fulcrum operation unit 165L is the right side (the user's right hand side is on the back) viewed from the opposite user. It has an R fulcrum operation unit 165R.

[2. Shoulder motion part and fulcrum motion part]
Here, the shoulder operation unit 155 and the fulcrum operation unit 165 will be specifically described with reference to FIGS. 2 and 3. FIG. 2A is a schematic perspective view of the bed apparatus 1, and FIG. 3 is a top view. Further, when the head side of the bed apparatus 1 is H and the foot side is F, the right side is R and the left side is L.

Here, the shoulder operation unit 155 is composed of an L shoulder operation unit 155L provided on the left side and an R shoulder operation unit 155R provided on the right side, and the fulcrum operation unit 165 is an L fulcrum operation provided on the left side. 165L, and an L fulcrum operating unit 165L provided on the right side.

As a method of realizing the shoulder operation unit 155 and the fulcrum operation unit 165, for example, the following cases can be considered.

(1) When the floor of the bed is divided (when it is composed of a movable floor)
For example, it is assumed that the floor portion 10 forming the bottom is divided and each floor moves (composed of a movable floor). And it is a method of providing a power source (for example, an actuator) on the movable floor. in this case,
(A) A power source is provided on each of the divided movable floors.
(B) One power source is provided for each of the movable floor on the shoulder side (shoulder operation unit 155) and the movable floor on the thigh side (fulcrum operation unit 165). In this case, the left/right switching mechanism or switch is used to switch between the left and right. In the present embodiment, in the turning motion, the normal shoulder motion unit 155 and the fulcrum motion unit 165 are diagonally moved. That is, since it is sufficient to operate one of the left and right sides, such a configuration may be used.
(C) One power source is used, and the cam mechanism and the wire are connected to the respective operating parts to operate. Normally, since the shoulder operation unit 155 and the fulcrum operation unit 165 move in a diagonal position together, such a configuration may be adopted when the two movement timings are the same.

(2) When a partially operable mechanism is used on the floor 10, for example, by placing an air cell on the floor 10 (between the mattress 20) and inflating the air cell simultaneously with raising the back, The shoulder operation unit 155 and the fulcrum operation unit 165 may be realized. A mechanism for lifting the user's body may be mounted instead of the air cell.

(3) When provided on or inside the mattress 20 For example, an object on a sheet composed of air cells may be placed on the mattress 20. That is, an air cell is provided between the mattress 20 and the user.

An air cell may be provided inside the mattress 20. This is realized by linking the control of the back raising operation and the mattress control, and performing the linked operation of the back raising and the mattress.

For example, FIG. 2B schematically shows a state in which an air cell is provided. An air cell is placed on the floor 10. In this figure, air cells 156L and 156R that operate as shoulder operation units are provided, and air cells 166L and 166R that operate as fulcrum operation units 165 are provided. By expanding the air cell, the same operation/effect can be realized.

Here, the shoulder motion unit 155 and the fulcrum motion unit 165 used during the turning motion may be automatically selected or may be configured to be switchable by the user. That is, the right shoulder portion and the left thigh portion (R shoulder operating portion 155R and L fulcrum operating portion 165L) may be set to operate, or conversely, the left shoulder portion and the right large portion. The thighs (L shoulder operation unit 155L and R fulcrum operation unit 165R) may be operated.

For these switching, for example, a hand switch may be provided as an operation button and can be freely set when the switch is switched, or the staff may switch it by a setting switch or the like. Further, the center of gravity of the patient may be detected and an appropriate operation unit may be operated.

[3. Main processing]
Next, the main process will be described. The main process is a process performed based on FIG. That is, in this embodiment, when the back-raising operation is detected (step S102), the back-raising operation process is executed (step S104). At this time, the turning operation processing is also executed (step S106). Here, the timing of the processing of performing the back-raising operation and the timing of performing the processing of the turning operation will be described as an example below.

[4. Example]
[4.1 First Embodiment]
First, control of the shoulder operation unit 155 and the fulcrum operation unit 165 in the case of the first embodiment will be described with reference to FIG.

FIG. 5 is a diagram for explaining operation timings of the back raising operation unit 135, the shoulder operation unit 155, and the fulcrum operation unit 165. The vertical axis represents angle and the horizontal axis represents time. Specifically, at time t100, the shoulder operation unit 155 and the fulcrum operation unit 165 on the diagonal side of the shoulder operation unit 155 start operating.

When the shoulder operation unit 155 operates, an operation of lifting the user's shoulder or neck (or both) is performed. Further, when the fulcrum operation unit 165 operates, a protrusion (bulge) is given to a part of the knee, thigh, or buttocks, so that the user's body partially contacts.

As a result, when the upper body is rotated, the fulcrum of the movement of the user's body is made in a part of the lower leg, and natural movement can be realized.

More specifically, the shoulder operation unit 155 and the fulcrum operation unit 165 operate in a symmetrical position and a diagonal portion. When the L shoulder operation unit 155L located on the left side of the user operates, the R fulcrum operation unit 165R that supports the right thigh operates. On the contrary, when the R shoulder operation unit 155R located on the right side of the user operates, the L fulcrum operation unit 165L that supports the left thigh operates.

In the present embodiment, when a back raising operation is detected, the shoulder operation unit 155 and the fulcrum operation unit 165 are lifted. In order to support the user, a part of the bottom (moving part) is lifted and an angle is formed as compared with other parts. This angle increases from time t100 to time t102. Note that, hereinafter, when the shoulder operation unit 155 and the fulcrum operation unit 165 are operating, it is assumed that the operation units at symmetrical positions are operating.

Then, when the angle is increased, the back raising operation is started (time t102). At this time, the angle (height) of the shoulder operation unit 155 and the fulcrum operation unit 165 is constant. For example, at this timing, the shoulder operation unit 155 and the fulcrum operation unit 165 are elevated by about 10 cm. When the back-raising angle gradually increases, this time, the shoulder operation unit 155 and the fulcrum operation unit 165 operate so as to become flat. That is, the angle decreases from time t104, and at time t106, the shoulder operation unit 155 and the fulcrum operation unit 165 do not rise, and the state becomes flat.

For example, at time t104, the back raising angle of the back bottom formed by the back raising motion unit 135 is about 45 degrees. Further, in the state of time t106, the back raising angle is approximately 50 degrees, and is an angle that can sufficiently support the patient without the support by the shoulder operation unit 155 and the fulcrum operation unit 165.

Note that these angles are merely examples, and include angles that can support the patient.

In the figure, the back raising itself is performed until the time t108, but after the time t106, the user is sufficiently supported by the back bottom, so that the state of each operation unit becomes a flat state.

FIG. 6 shows the state of the user in this case. As shown in FIG. 6, the shoulder on the right side of the user is lifted up, and the upper body of the patient is rotated. In addition, the fulcrum is formed near the diagonally left thigh, thereby supporting the user.

Subsequently, specific processing will be described with reference to FIG. 7. First, when the back raising operation is detected (step S152; Yes), the turning operation is started (step S154). As described above, the turning motion is performed by the shoulder motion unit 155 and the diagonal fulcrum motion unit 165 operating. As a result, a part of the bottom (floor portion) is raised, and it becomes possible to support the user.

After the turning operation is started, the back raising operation is started (step S156). Here, when the back-raising motion is greater than or equal to the predetermined angle (step S158; Yes), the ending process of the turning motion is performed (step S160).

Here, the turning operation ending process is a process of flattening a part of the bottom that is currently lifted for the turning operation.

Here, the process is continuously executed until the back raising operation is completed (step S162; No→step S158). That is, while the back-raising operation is being performed, the back-raising operation is being performed, but the turning operation is also being performed. Then, when the back-raising angle becomes equal to or larger than the predetermined angle, the turning operation ends.

When the back raising operation is finished, the back raising operation is finished (step S164). At this time, if the turning operation has not ended, a process of ending the turning operation is also executed.

As described above, in the case of the present embodiment, the turning operation is started before the back raising operation is started. Therefore, the turning operation enables the back raising operation with less burden on the patient.

[4.2 Second Embodiment]
Next, the second embodiment will be described. The second embodiment is an embodiment in which the knee bottom moves together with raising the back.

That is, before the back raising control unit 130 operates the back raising operation unit 135 to perform the back raising process, the knee raising control unit 140 operates the knee raising operation unit 145 to perform the knee raising process. The process flow in this case is shown in FIG. FIG. 8 is a replacement of the operation flow of FIG. 7 of the first embodiment, and the same processing is given the same reference numeral and its description is omitted.

Before the back raising operation of step S156 is started, the knee raising operation is started (step S172). In this knee raising operation, when the back raising angle is equal to or larger than the predetermined angle, the knee raising ending process is executed (step S174).

Here, various timings can be considered as the timing for ending the knee raising. For example, an example of timing is shown in FIG. In FIG. 9, the knee raising operation is started from time t154 after time t152 when the turning operation of the shoulder operation unit 155 and the fulcrum operation unit 165 is performed. The timing for starting this knee raising operation is performed before the time for starting the back raising operation.

Further, the end time is from time t158 to time t160 which is the end timing of the turning operation. That is, after time t160, the knee bottom and the waist bottom are flat. Therefore, even at time t162, it becomes flat except that the back is raised.

The timing of the knee raising operation unit 145 is an example and may be different. That is, the patient can be supported if the knee raising operation is performed at the timing when the back raising operation is performed.

For example, the knee raising operation unit 145 may not perform the ending operation at the above timing. That is, the knee bottom may be raised as it is without flattening the knee bottom.

[4.3 Third Embodiment]
Next, an embodiment in which the timings of the back-raising operation processing and the turning operation processing are changed will be described. The timing chart of the first embodiment is replaced with each of the embodiments.

Although not shown again for each embodiment, the processing shown in FIG. 7 may be changed as appropriate according to the operation timing based on the timing chart.

The second embodiment will be described with reference to the timing chart of FIG. The third embodiment is an embodiment in which the back raising motion unit 135, the shoulder motion unit 155, and the fulcrum motion unit 165 start their motions at substantially the same timing.

That is, the back-raising operation unit 135, the shoulder operation unit 155, and the fulcrum operation unit 165 are simultaneously executed at time t200 (note that the times are not necessarily the same, and the same effect can be expected even if there is some error. ).

Then, the shoulder operation unit 155 and the fulcrum operation unit 165 operate until time t202. Further, as for the end timing, the shoulder operation unit 155 and the fulcrum operation unit 165 start their operations from time t204 so that they become flat at time t206 when the back raising operation is completed.

As described above, various operation start timings of the back raising operation unit 135, the shoulder operation unit 155, and the fulcrum operation unit 165 can be considered.

For example, as shown in FIG. 11, after the back raising operation of the back raising operation unit 135 is completed (time t222), the shoulder operation unit 155 and the fulcrum operation unit 165 may be lowered. That is, the back-raising operation processing is completed first, and then the turning operation processing is completed. Therefore, from time t222 to time t224, the back raising motion is not performed while the shoulder motion unit 155 and the fulcrum motion unit 165 are performing the flattening motion.

Further, as shown in FIG. 12, the back-raising operation process may be executed while the turning operation process is being executed. That is, the back-raising operation process is not executed at the timing when the turning operation process is started at time t242. Then, the back raising operation processing is started in the middle of the turning operation processing (time t244).

At the timing (time t246) when the operations of the shoulder operation unit 155 and the fulcrum operation unit 165 are once completed, the back-raising operation unit 135 is the timing of performing the back-raising operation.

Further, as shown in FIG. 13, the back-raising operation process may be started first, and the turning operation process may be executed while the back-raising operation process is being executed. For example, the back-raising operation process (back-raising operation of the back-raising operation unit 135) is first executed at time t262, and the turning operation process is subsequently executed at time t264. In this case, it is preferable that the turning operation is performed at the timing when the back raising operation is performed. Therefore, the effect can be expected more preferably if the interval between the time t262 and the time t264 is not so large.

At this time, the back raising operation may be temporarily stopped before the turning operation. For example, when the back-raising angle formed by the back-raising operation unit 135 reaches about 5 degrees (time t264), the back-raising operation unit 135 stops once and performs a turning operation. Control may be performed such that the back raising operation is performed again when the shoulder operation unit 155 and the fulcrum operation unit 165 have risen to some extent.

As described above, in this embodiment, the back-raising operation processing (back-raising operation unit 135) and the turning operation processing (shoulder operation unit 155, fulcrum operation unit 165) can be performed at different timings.

[4.4 Fourth Embodiment]
Next, the fourth embodiment will be described with reference to the timing chart of FIG. The fourth embodiment is an embodiment in which the operation timings of the shoulder operation unit 155 and the fulcrum operation unit 165 are different in the turning operation processing.

First, the fulcrum operation unit 165 starts operation at time t300. Then, at time t302 after the operation of the fulcrum operation unit 165 is started, the operations of the shoulder operation unit 155 and the back raising operation unit 135 are started.

Further, the fulcrum operation unit 165 stops operating at time t304, but the shoulder operation unit 155 stops operating at time t306. Therefore, the fulcrum operation unit 165 and the shoulder operation unit 155 are time t308 and the time t310 when the operation starts again and all the operations end.

The fulcrum operation unit 165 and the shoulder operation unit 155 may be operated at different timings. Therefore, in FIG. 13, the back raising motion unit 135 and the shoulder motion unit 155 operate at the same timing at times t302 and t310, but may be at different timings.

Further, the fulcrum operation unit 165 and the shoulder operation unit 155 may end at the same timing. For example, the fulcrum operation unit 165 may also operate so as to end at time t310.

When performing the turning operation, it is preferable to first make a fulcrum for supporting the user's body and then perform the turning operation. Therefore, a higher effect can be expected by operating the fulcrum operation unit 165 first.

Since it is only necessary to support the user's body, the same effect can be expected in the case of the operation shown in FIG. 15, for example. That is, at time t350, the shoulder operation unit 155 is operated, but the shoulder operation unit 155 is stopped once at an angle that does not feel a burden on the user (time t352). Then, by operating the fulcrum operation unit 165 from time t354, the shoulder operation unit 155 is operated in earnest from the time when the fulcrum of the user is created (time t356).

As described above, the same effect can be expected for the shoulder operation unit 155 and the fulcrum operation unit 165 even if the timing is changed.

[4.5 Fifth Embodiment]
Next, the fifth embodiment will be described with reference to the timing chart of FIG. The fifth embodiment is an embodiment in the case where the back-raising operation process is terminated halfway.

First, at time t402, back raising operation processing (back raising operation unit 135) and rotation operation processing (shoulder operation unit 155, fulcrum operation unit 165) are executed. After that, for example, when the back raising operation ends at time t404, control is performed so that the turning operation also ends.

That is, when the operation of the back raising motion unit 135 is stopped at time t404, the shoulder motion unit 155 and the fulcrum motion unit 165 are controlled to be flat from time t404 to time t406. That is, the turning operation process is controlled to be ended.

Note that, in FIG. 16, the turning operation process ends at time t404 for convenience of explanation, but may end at a predetermined time. For example, as shown in FIG. 17, the shoulder operation unit 155 and the fulcrum operation unit 165 are stopped from time t404, but the operation is performed to be flat from time t410. This is because it is determined based on time whether the operation of the back-raising operation unit 135 was merely a temporary stop or an end.

In this case, it goes without saying that the method may be, for example, an operation instruction by the user instead of the time.

[4.6 Sixth Embodiment]
Next, the sixth embodiment will be described with reference to the timing chart of FIG. The sixth embodiment is an embodiment for explaining a reverse operation, that is, a back lowering operation as the back raising operation processing.

As shown in FIG. 18, first, the back lowering operation is executed from time t502. That is, as the back raising operation unit 135 operates, the back angle becomes smaller. At this time, the turning operation processing is also executed.

Specifically, from time t502 to time t504, the shoulder operation unit 155 and the fulcrum operation unit 165 operate, and the turning operation is performed. Then, at time t508 when the operation of the back raising operation unit 135 ends (the back angle is approximately 0 degree), the turning operation processing also ends. That is, the flattening operation is performed from time t506 to time t508.

As shown in the present embodiment, in the case of the back lowering operation, the turning operation is performed by the movements of the shoulder operating unit 155 and the fulcrum operating unit 165 at the timing when the back lowering operation is completed (the back angle becomes approximately 0 degrees). It will preferably be carried out.

In the back lowering operation described in the sixth embodiment, the operation timings of the back raising operation unit 135, the shoulder operation unit 155, and the fulcrum operation unit 165 are appropriately combined with the operations of the first to fifth embodiments. May be.

For example, as shown in FIG. 19, the timing of the back lowering operation and the timing of the turning operation may be deviated. For example, the back lowering operation is performed at time t522, but the timing at which the turning operation is performed is time t524.

Further, as for the ending timing, the turning operation is not completed at time t526, which is the timing at which the back lowering operation is completed, and the operation is completed at time t528, which is thereafter.

[5. Modification]
Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and a design etc. within the scope not departing from the gist of the present invention include.

In addition, the above-described embodiments may be appropriately combined and executed.
